With most casting today, the process starts at the computer, where a part has been designed and needs to be developed for precision sand-casting. The part is broken down to determine how many molds ...

The second process is used in the foundries for producing cast products. This is the oldest and simplest (in theory but not in practice) means of manufacturing shaped components. Other techniques, ...

Pouring molten metal into three-dimensional molds to make metal parts is the basis behind both sand and investment casting. But there are significant differences between these two methods. In sand ...

Gravity casting aluminum in permanent molds beats conventional sand and pressure die casting. Today, gravity-fed permanent metal molds can produce near-net-shape parts from a variety of aluminum ...
